In Sikhism, Guru is the source of all knowledge which attributed to Almighty by Guru Gobind Singh
The Sikh Gurus established Sikhism over the centuries, beginning in the year 1469. Sikhism was founded by the first guru, Guru Nanak, and subsequently, each guru, in succession, was referred to as "Nanak", and as "Light", making their teachings, in the holy scriptures, equivalent. There are a total of 11 gurus: ten human gurus and the eleventh, or current and everlasting Sikh Guru, is the integrated Sikh scriptures known as the Adi Granth or Guru Granth Sahib.
Sikhism was established by Guru Nanak and ten other Sikh Gurus starting in 1469. Guru Nanak was the first Guru, and Guru Gobind Singh, the 10th Guru, bestowed the Guruship forevermore to the Sikh holy scripture, the Guru Granth Sahib as the 11th Guru, the living word. The Khalsa is known as the Guru Panth, the final temporal Guru/leader of the Sikhs and embodiment of the Guru. Sikhs follow the teachings of the Gurus, which is believed upon remembering, leads to salvation.
The name "Nanak" was used by all the subsequent Gurus who wrote any sacred text in the Sikh holy scripture called the Guru Granth Sahib. The second Sikh Guru, Guru Angad, is also called the "Second Nanak" or "Nanak II". Sikhs hold that all subsequent Gurus carried the same message as that of Guru Nanak, and so they have used the name "Nanak" in their holy text, instead of their own names. Hence all are referred to as the "Light of Nanak".
